Graphics.DrawString specify opacity of text

Is it possible to specify the opacity of text written using the Graphics.DrawString method?

I'm doing something like this, but would like my text to be semi-transparent if it is possible.

Currently I'm doing this:

Graphics graphics = Graphics.FromImage(image);
graphics.DrawString("This is a watermark", 
    new Font("Arial", 40), 
    new SolidBrush(Color.Red), 
    0, 
    0);

Try:

int opacity = 128; // 50% opaque (0 = invisible, 255 = fully opaque)
using (var graphics = Graphics.FromImage(image))
using (var font = new Font("Arial", 40))
using (var brush = new SolidBrush(Color.FromArgb(opacity, Color.Red)))
    graphics.DrawString("This is a watermark", font, brush, 0, 0);
